I was using an old Maxtor 320Gb external HDD and that worked fine. Until the HD died. Then I tried a USB stick. The box couldn't see it. ('Available size 0Gb')I read up a bit and discovered it needs to be 20Gb+ for some sort of buffering reason. So I got a 32Bg stick. And formatted it in EXT3. And sure enough, it recognised it! ('Available size 28.2Gb') But 'Format storage' and 'Select the HDD for PVR' are both greyed out. So, it seems it knows there's a disk; it can see the 28.2GB; and it reports '100% available'. (It even correctly flags up that it's EXT3) But it won't actually use it.
Any suggestions/advice much appreciated.
